Table B7. Statistical results from the community composition (species replicated within each of 3 functional types; see text) data across the four metrics: (1) changes in relative (fraction within each plot) biomass 19542012; (2) changes in relative abundance 19542012; (3) relative biomass in 2012; (4) relative abundance in 2012. The interaction term (A, fire by functional type) indicates whether functional types differed in their response (either abundance or biomass) to fire. The direct effect of fire on N2 fixers (column B) evaluates the hypothesis that fire promotes the relative abundance or biomass of N2-fixing plants.
